| Upper GI Series What is an upper GI series? A GI or gastrointestinal series is an X-ray exam of the esophagus, stomach and part of the small intestine. The test is used to determine abnormalities in the upper gastrointestinal tract, such as ulcers or tumours. Preparation It is important that you don't eat or drink anything from midnight the night before your exam. If your stomach isn't empty the exam may have to be postponed. You will be asked to remove any metal that you may have on. What should I expect during the exam? You will be asked to swallow a barium drink. The barium fills your stomach and small intestine so that they can be seen on X-rays. During the exam, you will be asked to change your position or hold your breath for a few seconds. The study lasts approximately 45 minutes. An exam involving your small intestine will take longer. After the exam You may eat after the exam is over. It's important to drink plenty of fluids to avoid constipation from the barium. Note: your bowel movement may be tinged white for a few days. Tips for your exam * Wear comfortable clothes with no metal closures (cotton sweat suit, sports bra). * Don't eat or drink anything from midnight the night before your exam. Essential medication may be taken with a sip of water. |
